Narrative:

Climbed air carrier X to FL370 and thought that I had provided latitude spacing. However, the second air carrier Y did not get the parallel heading and the faster air carrier X overtook the lead air carrier Y.

Original NASA ASRS Text

Title: LESS THAN STANDARD SEPARATION BETWEEN SAME DIRECTION SAME ALT ACFT.

Narrative: CLBED ACR X TO FL370 AND THOUGHT THAT I HAD PROVIDED LAT SPACING. HOWEVER, THE SECOND ACR Y DID NOT GET THE PARALLEL HDG AND THE FASTER ACR X OVERTOOK THE LEAD ACR Y.
